What color do you like better planet?.

<P> Technology Channel (http://tech./) news: According to the information that the color of objects varies with temperature, starting from the black planet to the sun's red, the highest temperature of the star is said to be blue .color. .</ P> <P> on a clear night, we saw countless stars in the sky, the stars not much difference between the colors are basically yellow white. .But in fact, the stars are different colors. .If you use binoculars to observe the stars, you will see they have a variety of colors, very beautiful, very enjoyable. .So, why the stars have a different color? .</ P> <P> stars of different colors is determined by its own temperature of the decision. .The surface temperature of the different stars, it sends the color of light is different. .The results also show that the substance of the color is changed as the temperature increases, it seems a Road crossed the rainbow colors, from dark red to blue. .Each color corresponds to a certain temperature are: red about 600K; bright red about 1000K; pink about 1500K; light orange around 3000K; yellow about 5000K; yellow white, about 6000K; white about 12000K ~ 15000K; light blue, white, about 25000K .; luminous blue stars, the surface temperature of 25000-40000 degrees. .The sun's surface temperature is 6,000 degrees, it is its "middle age" when Long, appears to be yellow. .The brightest star in the sky is Sirius, its surface temperature is about 10000 ℃, so it looks like a clear white. .</ P> <P> star's life and human life are the same, after the decline from birth to adolescence, middle age and old age. .Stars from birth to middle age, the temperature rising until the middle of the peak, middle-aged period, the raw materials for thermonuclear reactions depleted, the temperature began to decline, until the death into a white dwarf. .In this process of change, the color of the star changes with the temperature changing. .The lower the surface temperature of the star is red, followed by yellow, the high surface temperature of stars appear white and blue and white. .China's famous historical "Historical Records" records, two thousand years ago in the Han Dynasty, Betelgeuse is yellow, but today we observed Betelgeuse is light orange, indicating the temperature of Betelgeuse is gradually reduced, it is .from the prime of life to old age. .</ P> <P> because we are very far from the stars, in addition to atmospheric refraction, so colorful stars with the naked eye can not see the light. .</ P> </ p>.
